摘　　要：从现代控制理论出发,将设置有粘弹性阻尼器的结构作为控制系统,建立其数学模型及状态方程,施加模拟的风荷载,在SIMULINK环境下进行动态仿真,得到受控结构在风荷载作用下的动态反应,然后将受控结构与非受控结构塔顶质点的动力响应进行比较。比较结果表明:粘弹性阻尼器有效减小了结构的振动反应,SIMULINK软件提高了输电塔仿真的质量和效果。According to modern control theory and regarding the structure with viscoelastic dampers as a control system, its mathematical model and state equation with analogue wind load are established. Dynamic simulation in SIMULINK environment is carried out, and the dynamic responses of the controlled structure affected by the wind load are obtained. Then the overhead particle＇s dynamic responses of the controlled structure and non-controlled structure are compared. The result shows that the viscoelastic damper effectively reduces the vibration responses of the structure, and SIMULINK improves the quality and effect of transmission tower simulation.
